Chainlens

Chainlens, built by Web3 Labs, is a blockchain explorer and analytics platform for EVM-compatible public and private chains (Ethereum, Hyperledger Besu, Quorum, Polygon, Avalanche, BNB Chain, etc.) as well as Substrate-based chains. It combines a user-friendly block explorer with powerful REST APIs for real-time transaction monitoring, smart contract verification, token and NFT tracking (ERC-20, ERC-721, ERC-1155), and integration of on-chain data with existing analytics and reporting pipelines. The API follows the EIP-3091 block explorer route conventions and is offered both as SaaS and self-hosted.

Chainlens publishes 38 APIs on the APIs.io network, including Account-Controller API, Account-Mapping-Controller API, Account-Tokens-Controller API, and 35 more. Tagged areas include Analytics, Blockchain, Block Explorer, Cryptocurrencies, and DeFi.

Chainlens’ developer surface includes documentation, getting-started guide, signup flow, pricing, engineering blog, GitHub presence, and 10 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/chainlens: open an issue to ask a question, or submit a pull request to add artifacts.
